This residence is located in a quiet corner of Bangkok, nested in the middle of authentic local housing just beside the Sathorn business district.
It wasn't too hard to find, and the owner Sutasinee was very helpful from the date I made the booking. (Do note that the picture of the aging house on Google Street View is not the correct one; it was in the next alley.)
I booked the "comfy room" in this "House of Sleep" for almost a week and it really lived up to its name. I was considering giving it 0 stars for making me not want to leave ;)
Sutasinee waited for me at the gate for check-in, even though my flight landed close to midnight. She also offered guidance throughout my stay.
It's close to a street market with excellent local food and not far from a supermarket, though the 7-Eleven was more than enough for me. The BTS station Chong Nonsi is also a stone's throw away.
I would definitely book this residence again when I come back to Bangkok.
